Abstract

"FLUIDO DE PERFURAçãO, E, MéTODO PARA PERFURAR UM FURO DE POçO EM UMA FORMAçãO SUBTERRâNEA". São descritos fluidos de perfuração baseados em óleo ambientalmente aceitáveis ou condescendentemente reguladores e métodos de utilizá-los na perfuração de um furo de poço em uma formação subterrânea. Os fluidos são capazes de satisfazer os regulamentos ambientais, enquanto mantendo reologia de lama oleosa e desempenho de lama oleosa total aceitáveis. Os fluidos consistem de uma emulsão invertida. A base ou fase contínua da emulsão consiste de ésteres misturados com olefinas isomerizadas e/ou outros hidrocarbonetos, tais como parafinas, óleos minerais ou triésteres de glicerídio ou suas combinações. Alternativamente, a emulsão tem uma base compreendendo olefinas isomerizadas misturadas com outros hidrocarbonetos, tais como alfa-olefinas, parafinas e naftenos lineares."DRILLING FLUID, AND METHOD FOR DRILLING A WELL HOLE IN AN UNDERGROUND FORMATION". Environmentally acceptable or condescendingly regulating oil-based drilling fluids are described and methods of using them to drill a wellbore in an underground formation. The fluids are capable of meeting environmental regulations, maintaining acceptable oily mud rheology and overall oily mud performance. The fluids consist of an inverted emulsion. The continuous base or phase of the emulsion consists of esters mixed with isomerized olefins and / or other hydrocarbons, such as paraffins, mineral oils or glyceride triesters or combinations thereof. Alternatively, the emulsion has a base comprising isomerized olefins mixed with other hydrocarbons, such as alpha olefins, paraffins and linear naphthenes.
